Total time is about 25 minutes (10 min prep + 15 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.
How do I store leftover Pan-Roasted Salmon with Dijon Mustard and Tarragon Cream?
Refrigerate in a covered airtight container for up to 3–4 days (FDA FoodKeeper guideline for cooked fish).
